IPS: Start IP address speed limit
IPE: the IP address of the end of speed limit
IPS and IPE not to fill 2 --- 254, otherwise the script run time will be longer, will take up some more memory.
Efficiency, if we adopt the u32 hash is no impact.
UP = 38: total upload bandwidth. Although my ADSL is 50KB / S, but for low-latency
DOWN = 380: total download bandwidth. Although my ADSL is 500KB / S, but for low-latency
UPLOADR = 2: single IP upload guaranteed bandwidth, 2KB / S is very OK.
UPLOADC = 15: maximum upload bandwidth of a single IP,msn video should be no problem.
UPLOADR2 = : to be "punished" after a single IP upload guaranteed bandwidth.
UPLOADC2 = : to be "punished" after the largest single IP UDP upload bandwidth, usually no more than 6KB / S
DOWNLOADR2: to be "punished" after the download guaranteed bandwidth of a single IP
DOWNLOADC2: to be "punished" after the maximum bandwidth to download a single IP
